D49.519 - Neoplasm of unspecified behavior of unspecified kidney

Version 2023
ICD-10:D49.519
Short Description:Neoplasm of unspecified behavior of unspecified kidney
Long Description:Neoplasm of unspecified behavior of unspecified kidney
Status: Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (D50–D89)
    • Neoplasms of unspecified behavior (D49)
      • Neoplasms of unspecified behavior (D49)

D49.519 is a billable ICD-10 code used to specify a medical diagnosis of neoplasm of unspecified behavior of unspecified kidney. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

The following anatomical sites found in the Table of Neoplasms reference the parent code D49.51 of the current diagnosis code given the correct histological behavior: Neoplasm, neoplastic calyx, renal ; Neoplasm, neoplastic kidney (parenchymal) ; Neoplasm, neoplastic kidney (parenchymal) calyx ; Neoplasm, neoplastic kidney (parenchymal) hilus ; Neoplasm, neoplastic kidney (parenchymal) pelvis ; Neoplasm, neoplastic parenchyma, kidney ; Neoplasm, neoplastic pelvis, pelvic renal ; etc

Unspecified diagnosis codes like D49.519 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Table of Neoplasms

The parent code D49.51 of the current diagnosis code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.
